What is the interest withholding rate between Bulgaria and United Kingdom?

The Bulgaria-United Kingdom tax treaty reduces the withholding rate on interest payments to 0%. This means interest paid between residents of these two countries is exempt from withholding tax at source. This is particularly beneficial for cross-border debt financing and bank deposits. The 0% rate still requires proper documentation — it does not apply automatically. Interest is fully exempt — Bulgaria has 1 such treaties in its network.
